Zix Corporation Sets Record in Replacement Wins for Fifth Consecutive Year

Volume of Zix licensed seats from replacement wins increases by more
than 200 percent year-over-year

DALLAS--(BUSINESS WIRE)--Mar. 1, 2016--
Zix
Corporation (ZixCorp), (NASDAQ: ZIXI), the leader in email
encryption services, announces that in calendar year 2015 the company
increased its total number of replacement wins for the fifth consecutive
year and increased the volume of Zix® licensed seats from
replacement wins by 212 percent from calendar year 2014. A replacement
win is the signing of a new customer that previously used a competing
email encryption solution. A transparent, mobile-friendly user
experience, proven policy filters and a trusted reputation were top
reasons customers switched to Zix
Email Encryption.

More than 13,500 customers trust ZixCorp to protect sensitive health,
financial and personal data, as well as confidential corporate
information. Recognized for its industry-leading ease of use, Zix Email
Encryption enables senders and recipients using ZixGateway®
to exchange secure email without any passwords or extra steps. Making
the user experience more convenient, customers can use Zix content
filters to automatically scan and encrypt emails with sensitive data,
allowing employees to skip the hassle and worry associated with
determining whether emails should be encrypted.

“You don’t have to be a security professional to realize data protection
is becoming more prevalent with the increased awareness of cybersecurity
threats. Ease of use is imperative to wide-spread adoption, and through
our trusted community, Zix makes email encryption as easy as regular
email,” said David
Wagner, Chief Executive Officer of ZixCorp. “Our consistent
increase in replacement wins validates that businesses place value in
our innovative, community approach and have confidence in us to best
protect communication and relationships with customers and partners.”

ZixCorp’s replacement wins in 2015 were strongest in the healthcare and
financial services industries. Examples of companies that replaced their
existing solution with Zix Email Encryption include:

Consumers Mutual Insurance of Michigan

Continental Title Company

Floyd County Medical Center

Kansas Surgery and Recovery Center

Ohio District 5 Area Agency on Aging

RCB Bank

Towne Mortgage Company

Pyramid Federal Credit Union

Among the calendar year 2015 replacement wins, 41 percent were with
enterprise-size customers, defined as organizations with 1000 employees
or above. Strategic partners, value added resellers (VARs) or managed
service providers (MSPs) closed 73 percent of replacement wins in the
calendar year 2015.

“Our partner program is robust with nearly 400 VARs and MSPs and
valuable strategic partners like Cisco and Google. Together we are
expanding the presence of Zix Email Encryption and bringing our
innovative, easy to use solutions to the market,” said Wagner. “Yet,
there is still great opportunity for growth, and we will continue to
deliver best-in-class solutions and collaborate with our partners for
mutually beneficial success.”
